Karst is a type of landscape formed by the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by features such as sinkholes, caves, and underground drainage systems. Karst landscapes are significant in hydrogeology for understanding groundwater flow, the formation of aquifers, and the unique ecosystems that develop in such environments.
